擴展ASCII

Question

當我嘗試保存在Eclipse中的.java文件與擴展ASCII字符，例如█返回以下錯誤

Save could not be completed. Try File >Save as if the problem persists 
Reason: 
Some characters cannot be mapped using "Cp1252" character encoding. 
Either change the encoding or remove the characters which are not 
supported by the "Cp1252" character encoding. 

而且我在該對話框中選擇將文件保存爲UTF-8。如果我這樣做，eclipse會繼續編譯正確嗎？或者有可能我會介紹錯誤？

Answer 1

使用unicode，不擴展ascii。

http://en.wikipedia.org/wiki/List_of_Unicode_characters#Block_elements列出了ASCiiesque塊字符。
